This excursion, named “The Hot and Cold of Killiney Geology” will take place on Saturday 30th August.
It will be led by Prof. John Walsh and Dr Sam Kelley.
Meet at Killiney DART Station at 09:30 with the excursion expected to take between 3 and 4 hours.
The plan is to walk along the beach looking at hard rocks and glacial sediments. This will be followed by a walk from the beach to the top of Killiney Hill (150m). The latter is along a good path, but in places it can become a stiff walk up steps.
The hard rock side of things will involve looking at the contact of the Leinster Granite, including a variety of granites together with associated contact and regional metamorphic rocks. We’ll examine evidence for the nature and timing of granite intrusion (ca 405My old) relative to the Caledonian Orogeny. The glacial geology of the Killiney area is complex, and as we’ll see, the glacial sediments backing Killiney Beach have been modified by glacio-tectonic processes, resulting in features commonly seen within faulted or tectonised rocks, such as faults and folds.
